How to programmatically set django select box?

Question

I have a model with a select box and I want to set it while saving the form in django.

I want users to be able to generate additional model updates, and one model I want to update has a selection box. I know the value that I want this selection field to be, but when I create a new model object, how to set the selection field in the code?

For instance -

Let's say I want to create a new Auto object, and I conclude if the car is one of the options Luxury, Economy or Standard.

I want to set the value of this selection field in code before saving the model object ...

Any clues?

Thanks in advance.
